Fixes http://autobuild.buildroot.net/results/acf/acfefc4f0f23ef646094ec427c9502eab7b86736/
Corrects a number of issues with the openssl handling:
- Libraries have to be listed after the object files using them, so pass
openssl linker statements in LIBS rather than COPT
- Openssl support library is libcrypto, not libcrypt
- Openssl need zlib
